Class RoutineSummaryEdge

Object

gudusoft.gsqlparser.dlineage.dynamicsql.RoutineSummaryEdge

public final class RoutineSummaryEdge
extends Object

One boundary→boundary symbolic edge of a RoutineSummary (design routine-summary-scc-design.md §2.2): the reachability quotient of the routine's analyzed relation graph, interior nodes (locals, cursor/record columns, intermediate result sets, function hops) composed away.

Relation semantics mirror the inline engine: a boundary pair connected by at least one all-fdd path carries an fdd edge, and a pair connected by at least one path containing an fdr hop carries an fdr edge — the two COEXIST exactly as dlineage's own fdd/fdr relationships do (never OR-merged; §4.1 ROW-dominates applies per chain, not per pair).

Modifier and Type	Class and Description
static class	RoutineSummaryEdge.Endpoint One boundary endpoint: kind + resolved parent name + column name.
static class	RoutineSummaryEdge.EndpointKind Boundary endpoint classes of the B2 quotient (§2.2 endpoint table).

Field Summary

Fields

Modifier and Type	Field and Description
static String	OBSERVED_FUNCTIONS_TOP B5 advisory-metadata top: observed function names exceeded the finite bound.
static String	TRANSFORM_TOP Deprecated. use OBSERVED_FUNCTIONS_TOP.

Constructor and Description
RoutineSummaryEdge(RoutineSummaryEdge.Endpoint source, RoutineSummaryEdge.Endpoint target, String relationType, Set<String> functions)

Method Summary

Modifier and Type	Method and Description
boolean	equals(Object o) Identity is (source, target, relationType) — §2.5 edge identity; the observed-function set is advisory metadata joined by union, not identity.
Set<String>	getFunctions() Deprecated. use getObservedFunctions(); retained for source compatibility with the B2/B3 summary API.
Set<String>	getObservedFunctions() Unordered advisory union of function names observed on contributing value paths.

Field Detail

OBSERVED_FUNCTIONS_TOP

public static final String OBSERVED_FUNCTIONS_TOP

B5 advisory-metadata top: observed function names exceeded the finite bound. The candidate edge survives widening; function order/path attribution was never claimed.

Method Detail

getSource

public RoutineSummaryEdge.Endpoint getSource()

getTarget

public RoutineSummaryEdge.Endpoint getTarget()

getRelationType

public String getRelationType()

getObservedFunctions

public Set<String> getObservedFunctions()

Unordered advisory union of function names observed on contributing value paths. It is not an ordered transform descriptor.

getFunctions

@Deprecated
public Set<String> getFunctions()

Deprecated. use getObservedFunctions(); retained for source compatibility with the B2/B3 summary API.

isObservedFunctionsTop

public boolean isObservedFunctionsTop()

isTransformTop

@Deprecated
public boolean isTransformTop()

Deprecated. use isObservedFunctionsTop().

equals

public boolean equals(Object o)

Identity is (source, target, relationType) — §2.5 edge identity; the observed-function set is advisory metadata joined by union, not identity.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()
